危険がある。[0003] The contaminants to be removed by cleaning usually include fine powders such as metals, resins, and glass, dusts, ionic substances and the like derived from raw materials generated during processing of each part. For cleaning, an organic solvent such as halogenated hydrocarbon, petroleum hydrocarbon and alcohol, or an aqueous cleaning agent aqueous solution containing a surfactant is usually used. Organic solvents commonly have environmental problems and a problem that ionic substances cannot be removed effectively, and petroleum hydrocarbons and alcohols are liable to catch fire.

る危険がある。[0004] On the other hand, an aqueous cleaning solution containing a surfactant has the ability to remove substantially all contaminants, has no risk of air pollution, and is safe in handling, but fully exhibits and maintains its cleaning ability. To achieve this, the detergent concentration is generally 1 w / v
Must be washed at% or more. In addition, there is also a problem that it is difficult to remove contamination in a narrow gap such as a bag hole. The cleaning agent set to a high concentration is disadvantageous because the cost increases and the cost of treating the waste liquid also increases. The use of fluorine-based and silicone-based surfactants with relatively low concentration and high surface activity is also conceivable. .

にある汚染物の洗浄能力が十分でない。 Detailed Discussion Polyoxyethylene alkyl ether type surfactants are known as a kind of nonionic surfactant. Normally, this type of nonionic surfactant has a long chain as a hydrophobic group, that is, an alkyl having 12 or more carbon atoms, and a polyoxyethylene chain having 5 to 20 ethylene oxide units as a hydrophilic group. These common surfactants have a high concentration, for example, 1 w /
In many cases, it is used at a concentration of v% or more, so that an extra load is applied to the wastewater treatment equipment and the ability to clean contaminants in a narrow space such as a bag hole is not sufficient.

It has a polyoxyalkylene chain with two oxypropylene blocks.

It can be produced by addition polymerization. The resulting addition polymer is a homopolymer of ethylene oxide (EO) when there are no propylene oxide (PO) units,
In the case of ４4, it is a block copolymer of EO and PO.
Either EO or PO may be added first, so the terminus may be either PO or EO units.

を用いることができる。The medium-chain fatty alcohol having 6 to 10 carbon atoms can be produced by reducing fatty acids containing a large amount of medium-chain fatty acids such as coconut oil fatty acids. Since the raw material is coconut oil which is a natural product, the fatty alcohol obtained therefrom is a mixture containing alcohols having different carbon numbers in various ratios. Fatty alcohols used as initiators have less than 6 and 10 carbon atoms from such mixtures.
Although it is possible to remove more components or to isolate and use a fatty alcohol having a desired number of carbon atoms, a mixture can be used as long as it contains 80% by weight or more of a fatty alcohol having 6 to 10 carbon atoms.

In this case, it is necessary that the aqueous solution contains the detergent at a concentration of at least 200 mg / L in order for the detergent to sufficiently exhibit its cleaning ability, and a concentration exceeding 5000 mg / L is disadvantageous in economical and drainage measures. In addition, it is not desirable because it adds an extra load to the rinsing operation.
